Hello, While working through the codebase familiarizing with certain aspects of the workflow, I noticed that Ruby still contain code and definitions that wrap around NT vs 9X code. While is not clear from the SupportedPlatforms wiki page: http://redmine.ruby-lang.org/wiki/ruby-19/SupportedPlatforms mswin32 can be identified as Windows 9X. Keeping win9x code or API usage can impact any further improvement in Windows area as limit our abilities to take advantage of these newer functionality. Having said this, could be possible we raise the bar on _WIN32_WINNT to minimum 0x0500 ? -- Luis Lavena AREA 17 - Perfection in design is achieved not when there is nothing more to add, but rather when there is nothing more to take away.
